Personally, I feel like it depends upon why the thing is members only and if it was originally public or not. Like, if you publicly stream something but you lock the archive in a paywall, it deserves to be leaked. If it started out as members only thing then you shouldn't leak it. If it's members only for copyright reasons alone, like they'd release something like it publicly if copyright concerns didn't exist, it should be leaked as well. And if public streams depend on the information in the members only content, it should be leaked. As someone who has had to deal with lost media, paywalls tend to lower the potential for that content to survive long term.
